Bagpipes were especially popular. Lots of games were played including ones with eggs. These included tossing an egg between two people moving further apart during each throw - drop it and you lose. Another popular game was 'snapdragon' where you picked raisins or other dried fruit out of a tray of flaming brandy!
Shakespeare's play The Twelfth Night, was introduced as entertainment for the 12th night in 1601 or 1602.
Which ever guest got the piece with the bean (or pea) was named the King (or Queen) of Misrule and oversaw the evening of excessive drinking, bawdy songs, indecent gestures, and parodies of the church and its rituals. All this large fun capped off the 12 day celebration of Christmas. The following day was Epiphany.
